Result Both mutanolysin and lysozyme could successfully lyse the wall of bifidobacterium and extract the plasmid from Bifidobacterium.

结果球孢链霉菌发酵液与溶菌酶均成到质粒。

When the denatured reduced egg white lysozymes were renatured by dilution method, an observable amount of aggregate precipitate could be immediately formed.

当用复性液稀释复性原服变性蛋白溶菌酶时，会迅可观量的沉淀。

Method Bifidobacterium plasmid was extracted by mutanolysin from Streptomyces globisporus which could lyse the wall of bifidobacterium.The result was compared with that by lysozyme.

方法利用球孢链霉菌发酵的变溶菌素来消化双歧杆菌细胞壁，质粒，并与商业化溶菌酶法比较。
